The effects of morphine-neostigmine and secretin provocation on pancreaticobiliary morphology in healthy subjects: a randomized, double-blind crossover study using serial MRCP.
Trial report in World journal of surgery, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSecretin-stimulated magnetic resonance cholangiopancreatography (MRCP) is used for the diagnosis of sphincter of Oddi dysfunction (SOD), but it does not correlate well with sphincter of Oddi manometry. Serial MRCP following morphine-neostigmine provocation may be of value in the assessment of SOD, but the effects of these pharmacological agents on pancreaticobiliary morphology in healthy subjects have not been studied. The aim of the present study was to use serial MRCP to characterize the effects of morphine-neostigmine and secretin provocation on serum pancreatic enzyme responses and pancreaticobiliary ductal morphology in healthy subjects.
methodsFollowing a baseline scan and serum lipase and amylase assays, 10 healthy subjects were randomized in a double-blind manner to receive morphine (10 mg intramuscularly [IM]), neostigmine (1 mg IM) and saline (intravenously [IV]); OR saline (IM), saline (IM) and secretin (1 U/kg IV). A MRCP study was performed at 5, 30, 60, 90, 120, 150, and 180 min thereafter, with blood samples taken every 60 min for 4 h. Pancreatic duct (PD) diameter, visible PD length, common bile duct (CBD) diameter, and gallbladder volume were recorded. Crossover studies were performed 10 days later.
resultsSerum pancreatic enzyme concentrations were significantly greater (amylase, P = 0.003; lipase, P = 0.04) after morphine-neostigmine than after secretin. Following morphine-neostigmine and secretin provocation, the mean (SEM) percentage increase in PD diameter was 28.7 (7.2) versus 12.9 (3.3); P < 0.0001, and visible PD length was 49.4 (11.5) versus 28.1 (8.2); P < 0.0001, respectively.
conclusionsThe effects of morphine-neostigmine were more pronounced than those of secretin in healthy subjects. The diagnostic utility of morphine-neostigmine stimulated serial MRCP for SOD merits further evaluation.
